Common Invasive Species

Posted on 15 Mar 2021

Several Alien and Invasive Plant Species (AIPS) can be found throughout South Africa, especially in areas where disturbances have taken place.


ENVASS has in its experience noticed several reoccurring species that be found in the Gauteng and Mpumalanga areas.


According to the National Environmental Management: Biodiversity Act (Act No. 10 of 2004) (NEM:BA), Section 75 states that the listed plants (as indicated in the updated NEM:BA Alien and Invasive Species List of 2020),  should be controlled and eradicated while causing the least harm to biodiversity and damage to the environment. Additionally, control and management programmes must be implemented to prevent, control or eradicate invasive species.


The Alien and Invasive Species Regulations (2014) and the updated NEM:BA Alien and Invasive Species List (2020), categorise problem plant species and define what should be done with them according to their level of threat. The list itself identifies 379 plant species that are legally declared invasive species that have been assigned to one of three categories:


  • Category 1a – Invasive species requiring compulsory control to combat or eradicate the species. No permits will be issued.
  • Category 1b – Invasive species requiring compulsory containment of the species. These plants are deemed to have a high invasive potential. No permits will be issued.
  • Category 2 – Invasive species regulated by listed activities. A permit is required to import, possess, grow, breed, move, sell, buy or accept as a gift any plants listed as Category 2 plants and it to be contained.
  • Category 3 – Invasive species that are subject to exemptions. Having it in possession and exercising control requires no permits is not prohibited. However, these species are prohibited for any activities outside of the listed exemptions.


The following three plants are easily identified in Gauteng and the surrounding areas:


Category 1b: Pennisetum setaceum (Fountain Grass):

Category 2: Acacia mearnsii (black wattle):


Category 1b: Cortaderia selloana (Pampas Grass):
